Referring to figure 4, an embodiment of the invention provides an aerosol-generating device comprising: the shell comprises a shell body 1, wherein the shell body 1 comprises a first opening 1210, a second opening 1110 and a mounting piece 2 positioned between the first opening 1210 and the second opening 1110, and the first opening 1210 and the second opening 1110 are arranged at two ends of the shell body 1; a heating element 4, the heating element 4 being connected to the housing 1 by the mount 2 and being operable to heat an aerosol-forming substrate located in a heating chamber into which the aerosol-forming substrate can be placed through the first opening 1210; a support 5, the support 5 being connected to the heating element 4 and being capable of disengaging the heating element 4 from the mounting 2; the heating element 4 can be detached from the housing 1 from the second opening 1110.

Specifically, the support 5 is connected to the heating element 4 and is capable of disengaging the heating element 4 from the mounting member 2 and from the housing 1 through the second opening 1110.

When the heating element 4 or the heating cavity where the heating element 4 is located needs to be cleaned, that is, smoke residue, condensed oil, coking and the like occur in the heating cavity, the supporting piece 5 can be detached from the aerosol generating device, because the heating element 4 is connected with the support 5 into a whole, the heating element 4 is also separated from the aerosol generating device along with the support 5, and is cleaned by adopting cleaning modes such as wiping, water washing, ultrasonic cleaning and the like, the tobacco tar remained in the aerosol generating device does not need to be cleaned by a special brush, and can be cleaned by a paper towel wiping mode or even cleaned by a clean water flushing mode so as to thoroughly clean the heating body and the heating bin, therefore, the aerosol cleaning device has a good cleaning effect, is convenient for users to use, has good suction experience, and also ensures the consistency of aerosol release.

In the embodiment provided by the invention, the support 5 and the heating element 4 are detachably connected, so that the heating element is separated from the aerosol generating device from the second opening, the support 5 and the heating element 4 can be cleaned respectively, the parts can be conveniently manufactured, installed and used, when the support or the heating element 4 needs to be replaced, only the support or the heating element 4 needs to be replaced independently, and the use cost of a user is reduced.

Referring to fig. 4, the present invention provides another embodiment in which the mounting member 2 includes a first tapered hole 3, and at least a portion of the fixing member for mounting the heating element 4 is fitted into the first tapered hole 3.

Specifically, the heating element 4 is fixed between the first opening 1210 and the first tapered hole 3 through a fixing member and extends towards the first opening 1210, the aerosol generating substrate is placed into the heating cavity from the first opening 1210, the aerosol generating substrate is heated by the heating element 4, and a part of the fixing member on which the heating element 4 is installed is matched with the first tapered hole 3, so that the situation that the smoke oil in the heating cavity permeates into the lower part of the installation member after the aerosol generating device is used for a period of time, the circuit connection is influenced, and the aerosol generating device is difficult to clean is avoided, the service life of the aerosol generating device is prolonged, and the aerosol generating device is convenient to clean.

Here, the inner diameter of the first tapered bore 3 may be tapered in the first direction a to both avoid penetration of soot from the heating chamber below the mount and to facilitate detachment and installation of the heating element 4 from the mount 2.

In the embodiment provided by the invention, the mounting member 2 is provided with an electrical connection contact which can be electrically connected with the heating element 4 or a detection unit for detecting information related to the heating element 4.

In the embodiment provided by the invention, referring to fig. 4, the aerosol generating device further comprises a coil support 8 and an electromagnetic coil 9, the electromagnetic coil 9 is arranged on the coil support 8, and the coil support 8 is detachably mounted at the first opening end of the housing 1; the coil support 8 is also provided with electrical connection contacts which can be electrically connected to a control unit of the device when the coil support 8 is mounted on the housing 1.

Specifically, the self-inductance of induction heating represents the physical quantity of the self-inductance capability of the coil, which is generally expressed by L and has the unit of henry, namely the inductance value which we often say; the magnetization of the induction heating is a result of the ordered arrangement of magnetic moments, the more ordered the magnetization is greater. Induction heating can take the following two forms:

(1) when the temperature detection element is not arranged in the aerosol generating device, the heating element is ferrite or austenite, an iron rod (namely a heating body) is inserted into the coil in the working process, the self-inductance coefficient of the iron rod is increased because the iron rod is magnetized, the magnetic induction intensity inside the electromagnet consisting of the coil and the iron rod is increased after the coil is electrified, and the magnetism of the electromagnet is enhanced under the same current. Then, when the temperature of the iron rod rises, the thermal motion of molecules is strengthened, the order of magnetic moments is reduced, and then the magnetism of the electromagnet (coil + iron rod) is weakened, and the self-inductance is reduced.

Self-inductance coefficient calculation formula:

L＝(u*S*N²) A first step of adding a first compound to the first compound,

l is the self-inductance;

u-medium permeability;

s is the coil sectional area;

n-number of turns of coil;

i-coil length.

According to the above formula, S, N, I is constant in the whole process, and only the permeability of the medium is changed, that is, the permeability of the iron rod is reduced due to the temperature rise of the iron rod, so that the L is reduced in the process, and the temperature change can be fed back according to the corresponding relation between the L reduction and the temperature. In other words, the temperature value can be detected by detecting the value of L without providing a temperature detecting element.

(2) When the temperature detection element is arranged in the aerosol generating device, the material of the heating element is not limited, the working process further refers to the electromagnetic induction law and the Lenz law, and the relationship between the inductance of the inductive element and the current and the voltage is as follows:

u (t) ═ L (di (t)/dt), wherein,

u (t) is a voltage value;

di (t)/dt is the current derivative with respect to time.

Wherein, U (t), di (t)/dt can be obtained by a sensor, so that an L value can be obtained to indirectly feed back the temperature.
